Label Adhesive Application

Label Adhesive Application

Problem: A manufacturing facility needed to apply glue precisely to labels on plastic containers, but they were experiencing significant quality control issues. Their existing AODD pump produced inconsistent and highly variable flow due to hydraulic pulsations inherent in the pump design. These flow fluctuations made it impossible to apply the adhesive evenly and accurately to the product labels, resulting in defective products, waste, and potential production slowdowns. The challenge was particularly difficult given the nature of the material—a water-based adhesive with high viscosity (110,000 centipoise)—which amplified the pulsation problems.

Descaling

Descaling

Problem: Rocky Mountain Steel Mills in Pueblo, CO uses two Myers/Aplex MA-240M quintuplex 200 HP plunger pumps to descale the raw material before it is sent through the forming rollers that create the final product. Each of these pumps produces 100 GPM at 2,200 psi. The reciprocating action and high pressure created by these pumps causes severe shaking of the pipes, valves, and pipe supports in the system. More critical to the operation, the pulsating flow can cause erratic descaling of the raw material. This erratic descaling can cause damage to the form rollers and can make it difficult for the steel mill to achieve consistent quality in their final product. This style of pump also requires a smooth flow of fluid to the inlet to work properly.

Advanced Materials Facility

Advanced Materials Facility

Problem: An advanced materials facility based in the Greater Toronto Area was hesitant to include dampeners in their operation as they hadn't had luck with them previously. Blacoh asked to see the installation. Upon further investigation, we discovered the customer had one uncharged dampener for two pumps (photo below), and it was located well outside the recommended 10 pipe diameter rule. This is a prime example of the importance of Size, Location, and Charge in regards to dampener installation.

Facilities Maintenance

Facilities Maintenance

Problem: Our customer moved into their new building which did not have a pressure reducing valve in the water main and the system pressure in the building was around 90 psi. The owner's office is near the men's restroom. Every time the urinal was flushed, extreme water hammer occurred. This was very aggravating to the owner and he was afraid that the water hammer might cause a pipe to rupture and flood the building.

Paper Industry

Paper Industry

Problem: A leading paper manufacturer located in Japan uses air operated double diaphragm (AODD) pumps to inject process chemicals into a mixing tank. The low viscosity of the liquid, less than 10 centipoises, makes the chemical in this particular application very susceptible to the reciprocating action of the pumps. This makes it extremely difficult to maintain any type of accuracy when introducing the chemical into the batch. As a result, the quality and consistency of the final product suffers.

Diaphragm Life

Diaphragm Life

Problem: A manufacturer of metal soup cans located in New Jersey uses (8) 2" air diaphragm pumps to transfer the product which is used to line the cans. The suction of the pump is attached to the bottom of a 35' tall tank. The air operated diaphragm pumps are fitted with expensive PTFE diaphragms. The diaphragms were failing prematurely which resulted in loss of product, excessive downtime, and expensive part replacement. Additionally, leakage was occurring at the pump's clamping bands and the pumps were noisy during operation.
